Scientific Investigation, Reasoning and Logic

1
Scientific Investigation, Reasoning and Logic

• SOL K.1, 1.1, 2.1, 3.1, 4.1, 5.1

2
Observing

• Direct Observations
• Using senses
• Simple instruments
• Repeated to improve accuracy
• Predictions
• Conclusions (inferences)

3
Make Observations

• Write down observations of the two balls using
  your five senses

4
Hypothesizing

• Question is developed using observations
• Questions are developed to form hypotheses
• Cause and effect relationships

5
Make a Hypothesis

• If both balls are dropped at the same time then
  _______
• _________________

6
Using Variables in Experimentation

• Simple experiments are conducted to answer
  questions
• Dependent and independent variables
• Dependent the variable that responds in an
  experiment
• Independent the variable that is purposely
  changed.

7
What is your Variable??

• Name the dependent and independent variables in
  your experiment.

8
Measuring

• Length, mass, volume
• Metric units
• English units
• Use to collect data
• Use appropriate instruments

9
Measuring Activity

• What can you measure in your experiment?
• Why is measuring important?

10
Communicating

• Simple graphs
• Orally
• Pictures/diagrams
• Written statements
• Numbers
• Gathering data
• Charts

11
Communicating Activity

• How can you communicate your results of your
  experiment?

12
Inferring

• Inferences (a conclusion based on evidence)
• Conclusions
• Distinction among
• Observations
• Conclusions
• Predictions

13
Inferring Activity

• What can you infer based on your results?

14
Interpreting, Analyzing, Evaluating Data

• Unusual or unexpected results are recognized
• Predictions are based on data

15
Classifying Sequencing

• Classified and arranged according to properties
• Classification key

16
Classifying Sequencing Activity

• Sort items by characteristics into two groups
• Take two groups and sort into two more groups

17
Designing, Constructing, Interpreting Models

• Simple physical models are constructed
• Examples
• Play dough models of plants
• Cells from everyday items

18
Parts of the Scientific Method

• Problem/Question
• Hypothesis
• Experiment
• Collection of data
• Evaluate data (Conclusion)
• Analysis
• Re-test

19
How can you incorporate the Scientific Method
into your class?

• With your group brainstorm ways you can
• incorporate the scientific method into your class

20
Scientific Method

• Use the language everyday, every subject
• Use the Scientific Method to solve problems in
  everyday events
• Use inquiry whenever possible (5Es)
• Science projects
• Use Scientific method in all activities and
  lessons in science.
